CICADELLINAE: PART 2. NEW WORLD CICADELLINI 635 
27, 1937 (Richards and Smart) (BM). One male, Mandos, ‘“Uypairanga’”’, 
Rio Negro, 81 mi. from Mandos, Amazonas, Brazil, October, 1941 (August 
Rabaut) (AMNH). 
O. insipida, n. sp., is similar to O. alvarengai, n. sp., in the structure of the 
male genitalia, but differs slightly in the form of aedeagus. The species are 
readily separable externally, insipida being shorter and more robust, and by its 
heavily punctate crown, pronotum, scutellum, and forewings. 
Oragua furva, NEW SPECIES 
FiGuRE 515, PAGE 634 
Length of male 5.6 mm. Head with median length of crown slightly less 
than one-half interocular width and approximately one-third transocular 
width; ocelli located slightly before a line between anterior eye angles, sur- 
face coarsely punctate; antennal ledges with anterior margins slightly con- 
cave; transclypeal suture obsolete medially. Pronotum and scutellum coarsely 
punctate; forewing with membrane including only inner apical cell, abruptly 
delimited from remainder of surface, base of fourth apical cell located more 
proximally than base of third, wing surface densely punctate before mem- 
brane. Male pygofer with macrosetae occurring over most of surface except 
basidorsal portion (as in illustration of O. discoidula (Osborn) (fig. 516c); 
plates short for genus, not extending nearly as far posteriorly as pygofer, each 
with multiseriate macrosetae, pygofer process platelike, dorsoapical, ex- 
tending anteromesally; style extending posteriorly slightly farther than apex of 
connective, with lobe at midlength, apex bluntly rounded; aedeagus with a 
pair of very conspicuous apodemes (in addition to dorsal apodemes) ex- 
tending anterodorsally, shaft very slender, curved slightly dorsally ante- 
apically, acute at apex, without processes. Paraphyses absent. 
Anterior dorsum and forewings cinereous (brown or blackish with 
numerous sordid gray irregularly arranged small spots and areas); face 
fuscous with large paler irregular areas on clypeus and pale areas between 
muscle impressions, clypellus, genae, and lora marked with smaller irregular 
paler spots; thoracic pleura and legs pale brownish irregularly marked with 
darker. 
Holotype male, Tucumdn, Ciudad Universitaria, Argentina, 800 m., 
February 18, 1959 (VJ. F. G. Clarke) (USNM). 
O. furva, n. sp., is similar to O. discoidula (Osborn) in the structure of the 
male genitalia, but is smaller (less than 6.0 mm compared to approximately 
7.0 mm or more) and the apical uncurved portion of the aedeagus is not as 
long as in discoidula. Also, the pygofer process is wanting in discoidula. 
Oragua triplehorni, NEW SPECIES 
FIGURE 517, PAGE 636 
Length of male 5.6-5.9 mm, of female 6.3-6.4 mm. Head with median 
length of crown from slightly less than six-tenths to slightly more than six- 
tenths interocular width, and from slightly more than one-third to more than
